The BigInteger class is used for mathematical operations involving large integers with magnitudes too large for primitive data types. For example 100-factorial is 158 digits - much larger than a long can represent. BigInteger provides analogues to all of Java’s primitive integer operators, and all relevant methods from java.lang.Math as well as few other operations.



BigInteger is immutable. Therefore you can’t change its state. For example, the following won’t work as sum won’t be updated due to immutability.

BigInteger sum = BigInteger.ZERO;
for(int i = 1; i < 5000; i++) {

Assign the result to the sum variable to make it work.

sum = sum.add(BigInteger.valueOf(i));

The official documentation of BigInteger states that BigInteger implementations should support all integers between -22147483647 and 22147483647 (exclusive). This means BigIntegers can have more than 2 billion bits!
